5. Operating Instructions

Follow these steps for safe and effective operation of your HARDELL Mini Chainsaw.

5.1. Starting the Chainsaw:

1. Insert Battery: Ensure a fully charged battery is securely inserted into the chainsaw handle.
2. Engage Safety Lock: Press and hold the safety lock button (usually located near the trigger) with your thumb.
3. Activate Trigger: While holding the safety lock, press the main trigger to start the chainsaw. Release the safety lock once the chainsaw is running.
4. One-Hand Operation: The chainsaw is designed for comfortable one-hand operation due to its lightweight nature (approx. 3 lbs). Maintain a firm grip on the anti-slip rubber handle.

5.2. Cutting Techniques:

• Branch Pruning: For small branches, position the chainsaw firmly against the branch and apply steady, gentle pressure. Allow the chain to do the work.
• Wood Cutting: For larger wood pieces (up to 6 inches in diameter), ensure the wood is stable. Start the cut slowly, allowing the chain to bite into the material. The chainsaw can cut a 6-inch thick branch in approximately 4 seconds, with a chain speed of 83.3 ft/s (14m/s).
• Avoid Overloading: Do not force the chainsaw through material. If the motor slows significantly, reduce pressure.
• Battery Life: A fully charged 21V 2000mAh battery provides approximately 45-60 minutes of working time, or over 50 cuts on a 6-inch log, depending on wood hardness.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your chainsaw. Always disconnect the battery before performing any maintenance.

6.1. Chain Lubrication:

• The chainsaw requires manual chain lubrication. Fill the provided oil bottle with appropriate chainsaw bar and chain oil (not included).
• Apply a small amount of oil directly to the chain and guide bar before and during extended use to reduce friction and wear.

6.2. Chain Tension Adjustment:

• Proper chain tension is crucial for safe and efficient operation. A chain that is too loose can derail, and one that is too tight can cause excessive wear and motor strain.
• To adjust, loosen the guide bar nut slightly. Use the tensioning screw (if present, or manually adjust the guide bar position) to achieve proper tension. The chain should be snug against the guide bar but still able to be pulled freely by hand.
• Retighten the guide bar nut firmly.

6.3. Cleaning and Storage:

• After each use, remove the battery and clean the chainsaw. Use a brush or compressed air to remove sawdust and debris from the guide bar, chain, and motor vents.
• Wipe down the exterior with a damp cloth. Do not use harsh chemicals.
• Store the chainsaw and batteries in the provided carrying case in a dry, cool place, away from direct sunlight and moisture.
• For long-term storage, ensure batteries are partially charged (around 50%) to prolong their lifespan.
